Electric servo c-type robot welding gun

Abstract

The invention relates to an electric servo C-shaped robot welding clamp. The electric servo C-shaped robot welding clamp comprises a driving module, a protective cover, a substrate, an upper plate, a fixed electrode arm module, a movable electrode arm module, a water pipe module and a transformer module. The driving module includes a servo motor and a speed reducer; the fixed electrode arm module includes a welding clamp arm connecting bracket, an aluminum alloy welding clamp arm, a copper connecting block, a copper welding clamp arm, a fixed electrode rod and a fixed electrode cap; and the movable electrode arm module includes a movable electrode arm, a movable electrode rod, a movable electrode arm cover, a movable electrode cap, a linear guide rail, a plummer linear bearing, a ball screw and a push rod. The water pipe module includes a distributor, a water inlet pipe, a water return pipe, a fixed electrode arm water return pipe, a movable electrode arm water return pipe, a transformer water return pipe, a fixed electrode arm water inlet pipe, a transformer water inlet pipe, a movable electrode arm water inlet pipe and a water pipe mounting bracket; and the transformer module includes a transformer, a copper bar 1, a copper bar 2, a copper bar 3 and a soft copper bar. The electric servo C-shaped robot welding clamp adopts a modular servo technology, and is precise in control.

Description

technical field [0001] The invention relates to a robot welding device, in particular to an electric servo C-type robot welding tongs. Background technique [0002] At present, welding is a common processing technology in the automobile manufacturing industry. As one of them, spot welding is widely used in the automobile manufacturing industry. By clamping two pieces of metal, a large current is passed through a small contact surface instantly, melting and fusing the two pieces of metal, and the effect of solid connection is achieved after cooling. The spot welding process will not damage the internal structure of the workpiece, and there is no need to add other welding materials. Due to the different welding positions and postures, the requirements for welding tongs are also different, and they are generally divided into C-type welding tongs and X-type welding tongs. [0003] In recent years, the domestic automobile industry has developed rapidly, the degree of automation...

AI Technical Summary

Problems solved by technology

[0004] The current servo welding tongs generally adopt the following two methods: one is the cooperation of the servo motor and the synchronous toothed belt. Since the synchronous toothed belt is prone to jumping teeth during the operation, the control accuracy will not be high during the use of the welding tongs; the synchronous toothed belt Short service life results in short overall service life of welding guns

The other is the servo hollow motor, the only manufacturer of welding tongs, the market is monopolized, and the price of welding tongs is expensive
